HUGO GI INTHER, OF OHEMNITZ, SAXONY, GERMANY, ASSIGNOR OF ONE- HALF TO MATTHEE HERFURTH, OF SAME PLACE.

KNITTING- SPECIFICATION forming part of Letters Patent No. 253,922, dated February 21, 1882.

' Application filed November 20, 1880. (N model.)

To all whom it may concern Be it known that I, HUGO GiiNTHER, of Ohemnitz, in the kingdom of Saxony, in the Empire of Germany, have invented a new and Improved Knitting-Machine, (for which neither I nor any one with my consent or to my knowledge has any foreign patent,) of which inven tion the following is a specification.

Figure 1 is a front view of part of a knittingmachine, showing myimprovement. Fig. 2 is a similar view, showing the parts in a difierent position. Fig. 3 is a front View of a modification thereof; Fig. 4,21. top view of the said modification; and Fig. 5, a cross-section on the line 0 c, Fig. 4.

The object of this invention is to provide a knitting-machine such, for example, as the been withdrawn.

Lamb knitting-machine-with an adjustable needle-plate, and with mechanism for moving said needle-plate, so that at any one time the operator can shift the needle-plate, and with it the position of each needle, thereby producing certain changes in the design of the work produced, which without such shifting could not be brought about.

My invention consists in combining with the movable needle-plate certain locking devices and certain unlocking devices which are operated at will, all as hereinafter more fully described.

In the accompanying drawings, the letter A represents the reciprocating carriage of a Lamb knitting-machine. This carriageis moved back and forth in the usual manner by the means of a crank. 13 is one of the needle-plates, grooved to receive the latched needles. This needle-plate is placed upon the supportingframe 0, and capable oflateral movement between two posts or blocks, a and b, that form a part of the supporting-frame O. In Fig. 1 the needle-plate is shown as moved against the post a, and in Fig. 2 as moved against the post b. In either position the plate B islocked by one of a pair of spring-latches, D and E, whose projecting noses are by suitable springs, d, forced into the space between theneedle-plate and the post from which the needle-plate has Thus in Fig. 1 the latch E,

corresponding posts of the supporting-frame enters the upwardly-extending member of an elbow-lever, H, there being two such elbowlevers, one pivoted to each post, as shown. The carriage A receives in suitable apertures projecting pins g and I1, and whenever itis desired to shift the needle-plate the carriage is moved so far that one of the pins-say the pin g, as in Fig. 1reaches a projecting incline, t, of the nearest latch, D, and presses this latch down, as in Fig. 1, and after that, the move ment of the carriage being continued in the direction of the arrow shown in Fig. 1, the pin g strikes the outer arm of the lever H, and thereby causes said elbow-lever, by drawing on the pin F, to pull the needle-plate toward the post a, thus bringing it into the position shown in Fig. 1. Having been drawn toward the post a, the needle-plate holds the latch D down, but liberates the latch E, which now springs up, and locks the needle'plate by entering between the post I) and the said needleplate. The knitting can now proceed as long as desired with this position of the needleplate.

It is well known that the full stroke of the carriage A is not required in all species of knitting; and whenever the needle-plate is to be shifted again the carriage is moved so as to cause the pin 71. to actuate the latch E, and to draw the plate B back to the post I).

The modification which is shown in Figs. 3, 4, and 5 consists in substituting for the devices which move and lock the needle-plate, and that are shown in Figs. 1 and 2, analogous but slightly diflerent elements of a corresponding combination. According to this modification I connect with the back of the needleplate a vibrating lever, L, which is pivoted to jecting ends I and m, which can be struck by the pins 9 and h of the carriage A, and which, when struck,will cause the slide M to move in the direction of the carriage, and the lever L to be vibrated, and the needle-plate to be moved 'in the direction opposite to that in which the carriage is moved.

The lockingis performed by means of springcatches 1), that fall into notches that are out into the needle-plate. These spring-catches are lifted at the proper time by inclined portions 8 of the slide M, so as to allow the needleplate to move. Thus in the position shown in Fig. 3 a projecting pin, h, of the carriage has struck the end m of the slide M, and has thereby pushed theinclined portion 8 from under the nearest catch 12, lifting that out of the notch of the plate B, and permitting, as the motion of the slide M is continued, the movement of the plate B in the desired direction. The upper end of the lever L plays in a slot of the slide, so as to permit this slide to first lift the catch before the plate B will be actually moved. The other catch 12 drops into its notch the moment the needle-plate has been moved to the end of its stroke. a

I claim- 1. In a knitting-machine, the combination of a reciprocating carriage, A, having projecting pins g and h, with the needle-plate B, devices for moving the same, andwith two locking-catches, all arranged so that the needleplate will always belocked by oneof theoatohes, asset forth, and in position to be moved by one of the projecting pins of the carriage, substantially as specified.

2. The combination of the carriage A, having pins 9 and h, with needle-plate B, having pinsFand G, and with the leversH and springcatches D and E, all arranged to operate substantially as described.

The above description of my invention signed by me this 21st dayof September, A. D. 1880.
